A website that is focused on installing linux on ipods it is ipodlinux.org. They have an official installer that works with all ipods except for the new 2nd gen ipod nanos And version 1.3 of the old ipod nano or at least thats my experience. this installer was just an easy installer with the sole purpose to put linux on an ipod nano 1st gen.
Now for movies have 2 folders on ur desktop one is where ur original movie is the other ur destination folder use the converter and select ur movie when it asks for output folder SELECT UR SECOND FOLDER(destination one) now u can name it the same as ur first movie BUT NO MATTER WHAT it has to end it .avi or its just useless information
IF your still haveing issues with the converter go to
MoPiD 1.5 Series
Hope that helps
